 <p>Recurrent neural networks (RNN) are widely used for modelling sequential data, e.g., natural language sentences. This example describes how to implement a RNN application (or model) using SINGA's RNN layers. We will use the <a href="https://github.com/karpathy/char-rnn">char-rnn</a> model as an example, which trains over sentences or source code, with each character as an input unit. Particularly, we will train a RNN using GRU over Linux kernel source code. After training, we expect t [...]

 <p>Recurrent neural networks (RNN) are widely used for modelling sequential data, e.g., natural language sentences. This example describes how to implement a RNN application (or model) using SINGA's RNN layers. We will use the <a href="https://github.com/karpathy/char-rnn">char-rnn</a> model as an example, which trains over sentences or source code, with each character as an input unit. Particularly, we will train a RNN using GRU over Linux kernel source code. After training, we expect t [...]

-<p>There are two typical ways to implement autograd, via symbolic differentiation
-like <a href="http://deeplearning.net/software/theano/index.html">Theano</a> or reverse
-differentiation like
-<a href="https://pytorch.org/docs/stable/notes/autograd.html">Pytorch</a>. SINGA follows
-Pytorch way, which records the computation graph and apply the backward
-propagation automatically after forward propagation. The autograd algorithm is
-explained in details
-<a href="https://pytorch.org/docs/stable/notes/autograd.html">here</a>. We explain the
-relevant modules in Singa and give an example to illustrate the usage.</p>

-<p>There are three classes involved in autograd, namely <code>singa.tensor.Tensor</code>,
-<code>singa.autograd.Operation</code>, and <code>singa.autograd.Layer</code>. In the rest of this
-article, we use tensor, operation and layer to refer to an instance of the
-respective class.</p>
+<p>实现autograd有两种典型的方式,一种是通过如<a href="http://deeplearning.net/software/theano/index.html">Theano</a>的符号微分(symbolic differentiation)或通过如<a href="https://pytorch.org/docs/stable/notes/autograd.html">Pytorch</a>的反向微分(reverse differentialtion)。SINGA遵循Pytorch方式,即通过记录计算图,并在正向传播后自动应用反向传播。自动传播算法的详细解释请参阅<a href="https://pytorch.org/docs/stable/notes/autograd.html">这里</a>。我们接下来对SINGA中的相关模块进行解释,并举例说明其使用方法。</p>

-<p>Three attributes of Tensor are used by autograd,</p>
+<p>Tensor的三个属性被autograd使用:</p>
 <ul>
-<li><code>.creator</code> is an <code>Operation</code> instance. It records the operation that generates
-the Tensor instance.</li>
-<li><code>.requires_grad</code> is a boolean variable. It is used to indicate that the
-autograd algorithm needs to compute the gradient of the tensor (i.e., the
-owner). For example, during backpropagation, the gradients of the tensors for
-the weight matrix of a linear layer and the feature maps of a convolution
-layer (not the bottom layer) should be computed.</li>
-<li><code>.stores_grad</code> is a boolean variable. It is used to indicate that the gradient
-of the owner tensor should be stored and output by the backward function. For
-example, the gradient of the feature maps is computed during backpropagation,
-but is not included in the output of the backward function.</li>
+<li><code>.creator</code>是一个<code>Operation</code>实例。它记录了产生Tensor实例的这个操作。</li>
+<li><code>.request_grad</code>是一个布尔变量。它用于指示autograd算法是否需要计算张量的梯度。例如,在反向传播的过程中,线性层的权重矩阵和卷积层(非底层)的特征图的张量梯度应该被计算。</li>
+<li><code>.store_grad</code>是一个布尔变量。它用于指示张量的梯度是否应该被存储并由后向函数输出。例如,特征图的梯度是在反向传播过程中计算出来的,但不包括在反向函数的输出中。</li>
 </ul>
-<p>Programmers can change <code>requires_grad</code> and <code>stores_grad</code> of a Tensor instance.
-For example, if later is set to True, the corresponding gradient is included in
-the output of the backward function. It should be noted that if <code>stores_grad</code> is
-True, then <code>requires_grad</code> must be true, not vice versa.</p>
+<p>开发者可以改变Tensor实例的<code>requires_grad</code>和<code>stores_grad</code>。例如,如果将后者设置为True,那么相应的梯度就会被包含在后向函数的输出。需要注意的是,如果<code>stores_grad</code>是True,那么 <code>requires_grad</code>一定是真,反之亦然。</p>
 <h3><a class="anchor" aria-hidden="true" id="operation"></a><a href="#operation" aria-hidden="true" class="hash-link"><svg class="hash-link-icon" aria-hidden="true" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.6 [...]
-<p>It takes one or more <code>Tensor</code> instances as input, and then outputs one or more
-<code>Tensor</code> instances. For example, ReLU can be implemented as a specific Operation
-subclass. When an <code>Operation</code> instance is called (after instantiation), the
-following two steps are executed:</p>
-<ol>
-<li>record the source operations, i.e., the <code>creator</code>s of the input tensors.</li>
-<li>do calculation by calling member function <code>.forward()</code></li>
-</ol>
-<p>There are two member functions for forwarding and backwarding, i.e.,
-<code>.forward()</code> and <code>.backward()</code>. They take <code>Tensor.data</code> as inputs (the type is
-<code>CTensor</code>), and output <code>Ctensor</code>s. To add a specific operation, subclass
-<code>operation</code> should implement their own <code>.forward()</code> and <code>.backward()</code>. The
-<code>backward()</code> function is called by the <code>backward()</code> function of autograd
-automatically during backward propogation to compute the gradients of inputs
-(according to the <code>require_grad</code> field).</p>
+<p>它将一个或多个<code>Tensor</code>实例作为输入,然后输出一个或多个<code>Tensor</code>实例。例如,ReLU可以作为一个具体的Operation子类来实现。当一个<code>Operation</code>实例被调用时(实例化后),会执行以下两个步骤。</p>
+<p>1.记录源操作,即输入张量的<code>创建者</code>。
+2.通过调用成员函数<code>.forward()</code>进行计算。</p>
+<p>有两个成员函数用于前向和反向传播,即<code>.forward()</code>和<code>.backward()</code>。它们以<code>Tensor.data</code>作为输入(类型为<code>CTensor</code>),并输出<code>Ctensor</code>s。要添加一个特定的操作,子类<code>Operation</code>应该实现自己的<code>.forward()</code>和<code>.backward()</code>函数。在后向传播过程中,autograd的<code>backward()</code>函数会自动调用<code>backward()</code>函数来计算输入的梯度(根据<code>require_grad</code>字段的参数和约束)。</p>

-<code>Layer</code>. For example, convolution operation is wrapped into a convolution layer.
-<code>Layer</code> manages (stores) the parameters and calls the corresponding <code>Operation</code>s
-to implement the transformation.</p>

-<p>There are two typical ways to implement autograd, via symbolic differentiation
-like <a href="http://deeplearning.net/software/theano/index.html">Theano</a> or reverse
-differentiation like
-<a href="https://pytorch.org/docs/stable/notes/autograd.html">Pytorch</a>. SINGA follows
-Pytorch way, which records the computation graph and apply the backward
-propagation automatically after forward propagation. The autograd algorithm is
-explained in details
-<a href="https://pytorch.org/docs/stable/notes/autograd.html">here</a>. We explain the
-relevant modules in Singa and give an example to illustrate the usage.</p>

-<code>singa.autograd.Operation</code>, and <code>singa.autograd.Layer</code>. In the rest of this

+<p>实现autograd有两种典型的方式,一种是通过如<a href="http://deeplearning.net/software/theano/index.html">Theano</a>的符号微分(symbolic differentiation)或通过如<a href="https://pytorch.org/docs/stable/notes/autograd.html">Pytorch</a>的反向微分(reverse differentialtion)。SINGA遵循Pytorch方式,即通过记录计算图,并在正向传播后自动应用反向传播。自动传播算法的详细解释请参阅<a href="https://pytorch.org/docs/stable/notes/autograd.html">这里</a>。我们接下来对SINGA中的相关模块进行解释,并举例说明其使用方法。</p>

-<p>Three attributes of Tensor are used by autograd,</p>
+<p>Tensor的三个属性被autograd使用:</p>
 <ul>
-<li><code>.creator</code> is an <code>Operation</code> instance. It records the operation that generates
-the Tensor instance.</li>
-<li><code>.requires_grad</code> is a boolean variable. It is used to indicate that the
-autograd algorithm needs to compute the gradient of the tensor (i.e., the
-owner). For example, during backpropagation, the gradients of the tensors for
-the weight matrix of a linear layer and the feature maps of a convolution
-layer (not the bottom layer) should be computed.</li>
-<li><code>.stores_grad</code> is a boolean variable. It is used to indicate that the gradient
-of the owner tensor should be stored and output by the backward function. For
-example, the gradient of the feature maps is computed during backpropagation,
-but is not included in the output of the backward function.</li>
+<li><code>.creator</code>是一个<code>Operation</code>实例。它记录了产生Tensor实例的这个操作。</li>
+<li><code>.request_grad</code>是一个布尔变量。它用于指示autograd算法是否需要计算张量的梯度。例如,在反向传播的过程中,线性层的权重矩阵和卷积层(非底层)的特征图的张量梯度应该被计算。</li>
+<li><code>.store_grad</code>是一个布尔变量。它用于指示张量的梯度是否应该被存储并由后向函数输出。例如,特征图的梯度是在反向传播过程中计算出来的,但不包括在反向函数的输出中。</li>
 </ul>
-<p>Programmers can change <code>requires_grad</code> and <code>stores_grad</code> of a Tensor instance.
-For example, if later is set to True, the corresponding gradient is included in
-the output of the backward function. It should be noted that if <code>stores_grad</code> is
-True, then <code>requires_grad</code> must be true, not vice versa.</p>
+<p>开发者可以改变Tensor实例的<code>requires_grad</code>和<code>stores_grad</code>。例如,如果将后者设置为True,那么相应的梯度就会被包含在后向函数的输出。需要注意的是,如果<code>stores_grad</code>是True,那么 <code>requires_grad</code>一定是真,反之亦然。</p>

-<li>record the source operations, i.e., the <code>creator</code>s of the input tensors.</li>
-<li>do calculation by calling member function <code>.forward()</code></li>
-</ol>
-<p>There are two member functions for forwarding and backwarding, i.e.,
-<code>.forward()</code> and <code>.backward()</code>. They take <code>Tensor.data</code> as inputs (the type is
-<code>CTensor</code>), and output <code>Ctensor</code>s. To add a specific operation, subclass
-<code>operation</code> should implement their own <code>.forward()</code> and <code>.backward()</code>. The
-<code>backward()</code> function is called by the <code>backward()</code> function of autograd
-automatically during backward propogation to compute the gradients of inputs
-(according to the <code>require_grad</code> field).</p>
+<p>它将一个或多个<code>Tensor</code>实例作为输入,然后输出一个或多个<code>Tensor</code>实例。例如,ReLU可以作为一个具体的Operation子类来实现。当一个<code>Operation</code>实例被调用时(实例化后),会执行以下两个步骤。</p>
+<p>1.记录源操作,即输入张量的<code>创建者</code>。
+2.通过调用成员函数<code>.forward()</code>进行计算。</p>
+<p>有两个成员函数用于前向和反向传播,即<code>.forward()</code>和<code>.backward()</code>。它们以<code>Tensor.data</code>作为输入(类型为<code>CTensor</code>),并输出<code>Ctensor</code>s。要添加一个特定的操作,子类<code>Operation</code>应该实现自己的<code>.forward()</code>和<code>.backward()</code>函数。在后向传播过程中,autograd的<code>backward()</code>函数会自动调用<code>backward()</code>函数来计算输入的梯度(根据<code>require_grad</code>字段的参数和约束)。</p>

+<p>要构建GPU版的SINGA,计算机必须装备有Nvida GPU,而且需要安装CUDA driver(&gt;=384.81)、CUDA toolkit(&gt;=9)和cuDNN(&gt;=7)。以下两个Docker镜像提供了构建环境:</p>
+<ol>
+<li>apache/singa:conda-cuda9.0</li>
+<li>apache/singa:conda-cuda10.0</li>
+</ol>
+<p>构建环境准备好后,需要先导出CUDA版本,然后运行conda命令构建SINGA:</p>

+<p>若要上传到anaconda云端供他人下载安装,需要在 anaconda 上注册一个账号,才能<a href="https://docs.anaconda.com/anaconda-cloud/user-guide/getting-started/">上传包</a>:</p>
+<pre><code class="hljs css language-shell">conda install anaconda-client

+<p>将包上传到云端后,您可以在<a href="https://anaconda.org/">Anaconda Cloud</a>上看到,也可以通过以下命令查看:</p>
+<pre><code class="hljs css language-shell">conda search -c &lt;anaconda username&gt; singa

+<p>每个特定的SINGA软件包都由版本和构建字符串来标识。要安装一个特定的SINGA包,需要提供所有信息,例如:</p>
+<pre><code class="hljs css language-shell">conda install -c &lt;anaconda username&gt; -c conda-forge singa=2.1.0.dev=cpu_py36
+</code></pre>
+<p>为了使安装命令简单化,您可以创建以下附加包,这些包依赖于最新的CPU和GPU SINGA包:</p>
+<pre><code class="hljs css language-console"><span class="hljs-meta">#</span><span class="bash"> <span class="hljs-keyword">for</span> singa-cpu</span>

+<p>CMake选项的详细内容在本页最后一节解释,上面最后一条命令是安装Python包。你也可以运行<code>pip install -e .</code>,它可以创建符号链接,而不是将 Python 文件复制到 site-package 文件夹中。</p>
+<p>如果SINGA在ENABLE_TEST=ON的情况下编译,您可以通过以下方式运行单元测试:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> ./bin/test_singa</span>

+<p>SINGA使用opencl-headers和viennacl(版本1.7.1及以上)来支持OpenCL,它们可以通过如下方式安装:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">#</span><span class="bash"> On Ubuntu 16.04</span>
+<span class="hljs-meta">$</span><span class="bash"> sudo apt-get install opencl-headers, libviennacl-dev</span>

+<span class="hljs-meta">$</span><span class="bash"> sudo yum install opencl-headers, viennacl</span>
+</code></pre>
+<p>此外,你需要在你想运行OpenCL的平台安装OpenCL Installable Client Driver(ICD)。</p>
+<ul>
+<li>对于AMD和Nvidia的GPU,驱动包也应该安装与之匹配的OpenCL ICD。</li>
+<li>对于Intel的CPU和/或GPU,请从<a href="https://software.intel.com/en-us/articles/opencl-drivers">Intel官方网站</a>上获取驱动程序。请注意,该网站上提供的驱动程序只支持最新的CPU和Iris GPU。</li>
+<li>对于旧的Intel CPU,你可以使用beignet-opencl-icd包。</li>
+</ul>
+<p>请注意,目前不建议在CPU上运行OpenCL,因为运行速度会很慢。内存传输是以整数秒为单位的(直观来说,CPU上是1000毫秒,而GPU上是1毫秒)。</p>
+<p>更多关于建立OpenCL工作环境的信息可以在<a href="https://wiki.tiker.net/OpenCLHowTo">这里</a>找到。</p>
+<p>如果ViennaCL的软件包版本不是至少1.7.1,则需要从源码构建它:</p>
+<p>从<a href="https://github.com/viennacl/viennacl-dev">这个git repo</a>clone版本库,切换(checkout)到release-1.7.1分支,然后构建它,并把项目路径添加到PATH,再把构建的库文件添加到LD_LIBRARY_PATH。</p>

+<ul>
+<li><p>Q: 'import singa'阶段报错</p>
+<p>A: 请检查<code>python -c &quot;from singa import _singa_wrap</code>中的详细错误。有时是由依赖库引起的,比如protobuf有多个版本,cudnn缺失,numpy版本不匹配等问题。下面展示了不同情况下的解决方案</p>
+<ol>
+<li><p>检查cudnn和cuda。如果cudnn缺失或与wheel包的版本不一致,你可以下载正确的cudnn版本到~/local/cudnn/,然后:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> <span class="hljs-built_in">echo</span> <span class="hljs-string">"export LD_LIBRARY_PATH=/home/&lt;yourname&gt;/local/cudnn/lib64:<span class="hljs-variable">$LD_LIBRARY_PATH</span>"</span> &gt;&gt; ~/.bashrc</span>
+</code></pre></li>
+<li><p>如果是protobuf的问题。你可以将protobuf (3.6.1)从源码安装到本地文件夹,比如 ~/local/,解压tar文件,然后:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> ./configure --prefix=/home/&lt;yourname&gt;<span class="hljs-built_in">local</span></span>
+<span class="hljs-meta">$</span><span class="bash"> make &amp;&amp; make install</span>
+<span class="hljs-meta">$</span><span class="bash"> <span class="hljs-built_in">echo</span> <span class="hljs-string">"export LD_LIBRARY_PATH=/home/&lt;yourname&gt;/local/lib:<span class="hljs-variable">$LD_LIBRARY_PATH</span>"</span> &gt;&gt; ~/.bashrc</span>
+<span class="hljs-meta">$</span><span class="bash"> <span class="hljs-built_in">source</span> ~/.bashrc</span>
+</code></pre></li>
+<li><p>如果找不到包括python在内的其他类库,则使用<code>pip</code>或<code>conda</code>创建虚拟环境.</p></li>
+<li><p>如果不是上述原因造成的,请到<code>_singa_wrap.so</code>文件夹中查看:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> python</span>
+<span class="hljs-meta">&gt;</span><span class="bash">&gt; import importlib</span>
+<span class="hljs-meta">&gt;</span><span class="bash">&gt; importlib.import_module(<span class="hljs-string">'_singa_wrap'</span>)</span>
+</code></pre>
+<p>来检查错误信息。例如,如果是numpy的版本不匹配,错误信息会是:</p>
+<pre><code class="hljs css language-shell">RuntimeError: module compiled against API version 0xb but this version of numpy is 0xa
+</code></pre>
+<p>那么你就需要更新numpy到更高版本。</p></li>
+</ol></li>
+</ul>
+<ul>
+<li><p>Q: 运行<code>cmake ...</code>时出错,找不到依赖库。</p>
+<p>A: 如果你还没有安装这些依赖库,请先安装它们。如果你在系统文件夹之外的文件夹中安装了库,例如/usr/local,那您需要手动导出以下变量:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> <span class="hljs-built_in">export</span> CMAKE_INCLUDE_PATH=&lt;path to your header file folder&gt;</span>

+</code></pre></li>
+</ul>
+<ul>
+<li><p>Q: 来自<code>make</code>的错误,例如linking阶段的错误.</p>
+<p>A: 如果您的库文件在系统默认路径以外的其他文件夹中,则需要手动导出以下变量。</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> <span class="hljs-built_in">export</span> LIBRARY_PATH=&lt;path to your lib file folder&gt;</span>
+<span class="hljs-meta">$</span><span class="bash"> <span class="hljs-built_in">export</span> LD_LIBRARY_PATH=&lt;path to your lib file folder&gt;</span>
+</code></pre></li>
+</ul>
+<ul>
+<li><p>Q: 来自头文件的错误,例如'cblas.h文件不存在'</p>
+<p>A: 您需要手动将cblas.h的文件夹包含在CPLUS_INCLUDE_PATH中,例如:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> <span class="hljs-built_in">export</span> CPLUS_INCLUDE_PATH=/opt/OpenBLAS/include:<span class="hljs-variable">$CPLUS_INCLUDE_PATH</span></span>
+</code></pre></li>
+<li><p>Q: 在编译SINGA时,我收到错误信息<code>SSE2 instruction set not enabled</code></p>
+<p>A:您可以尝试如下指令:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> make CFLAGS=<span class="hljs-string">'-msse2'</span> CXXFLAGS=<span class="hljs-string">'-msse2'</span></span>
+</code></pre></li>
+<li><p>Q:当试图导入.py文件时,从google.protobuf.internal收到<code>ImportError: cannot import name enum_type_wrapper</code>。</p>
+<p>A: 您需要安装protobuf的Python绑定包,它可以通过如下方式安装:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> sudo apt-get install protobuf</span>
+</code></pre>
+<p>或从源文件编译:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> <span class="hljs-built_in">cd</span> /PROTOBUF/SOURCE/FOLDER</span>
+<span class="hljs-meta">$</span><span class="bash"> <span class="hljs-built_in">cd</span> python</span>
+<span class="hljs-meta">$</span><span class="bash"> python setup.py build</span>
+<span class="hljs-meta">$</span><span class="bash"> python setup.py install</span>
+</code></pre></li>
+<li><p>Q: 当我从源码构建OpenBLAS时,被告知需要一个Fortran编译器。</p>
+<p>A: 您可以通过如下方式编译OpenBLAS:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> make ONLY_CBLAS=1</span>
+</code></pre>
+<p>或者通过如下方式安装:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> sudo apt-get install libopenblas-dev</span>
+</code></pre></li>
+<li><p>Q: 当我构建协议缓冲区时,它报告说在<code>/usr/lib64/libstdc++.so.6</code>中没有找到<code>GLIBC++_3.4.20</code>?</p>
+<p>A: 这意味着链接器找到了libstdc++.so.6,但该库属于旧的GCC(用于编译和链接程序的GCC)版本。此程序依赖于新的libstdc++中定义的代码,而该代码属于较新版本的GCC,所以必须告诉链接器如何找到较新的libstdc++共享库。最简单的解决方法是找到正确的libstdc++,并将其导出到LD_LIBRARY_PATH。例如,如果下面命令的输出中列出了GLIBC++_3.4.20:</p>
+<pre><code class="hljs">  $ strings /usr/local/lib64/libstdc++.so.6|grep GLIBC++
+</code></pre>
+<p>那么接下来需要设置环境变量为:</p>
+<pre><code class="hljs">  $ export LD_LIBRARY_PATH=/usr/local/lib64:$LD_LIBRARY_PATH
+</code></pre></li>
+<li><p>Q: 当构建glog时,报告说 &quot;src/logging_unittest.cc:83:20: error: 'gflags' is not a namespace-name&quot;。</p>
+<p>A: 可能是由于安装的gflags用了不同的命名空间,比如 &quot;google&quot;,所以glog找不到'gflags'的命名空间。实际上建立glog并不需要gflags,所以你可以修改configure.ac文件来忽略gflags。</p>
+<pre><code class="hljs">  1. cd to glog src directory
+  2. change line 125 of configure.ac  to &quot;AC_CHECK_LIB(gflags, main, ac_cv_have_libgflags=0, ac_cv_have_libgflags=0)&quot;
+  3. autoreconf
+</code></pre>
+<p>执行上述命令后,就可以重新构建glog了。</p></li>
+<li><p>Q: 在使用虚拟环境时,每次运行pip install,都会重新安装numpy。但是,当运行<code>import numpy</code>时,numpy并没有被调用。</p>
+<p>A: 可能是由于<code>PYTHONPATH</code>造成的,在使用虚拟环境时,应将<code>PYTHONPATH</code>设置为空,以避免与虚拟环境本身的路径冲突。</p></li>
+<li><p>Q: 当从源代码编译PySINGA时,由于缺少&lt;numpy/objectarray.h&gt;,出现的编译错误。</p>
+<p>A: 请安装numpy并导出numpy头文件的路径为</p>
+<pre><code class="hljs">  $ export CPLUS_INCLUDE_PATH=`python -c &quot;import numpy; print numpy.get_include()&quot;`:$CPLUS_INCLUDE_PATH
+</code></pre></li>
+<li><p>Q: 当我在Mac OS X中运行SINGA时,报错 &quot;Fatal Python error:
+PyThreadState_Get: no current thread Abort trap: 6&quot;</p>
+<p>A: 这个错误通常发生在系统上有多个版本的Python,并且是通过pip安装的SINGA (通过conda安装时不会出现这个问题),例如,操作系统自带的版本和Homebrew安装的版本。PySINGA所链接的Python必须与Python解释器(interpreter)相同。 您可以通过 <code>which python</code> 检查您的解释器路径并通过<code>otool -L &lt;path to _singa_wrap.so&gt;</code>检查PySINGA链接的Python路径。要解决这个问题,请用正确的 Python 版本编译 SINGA。需要注意的是,如果您从源码编译 PySINGA,您需要在调用<a href="http://stackoverflow.com/questions/15291500/i-have-2-versions-of-python-installed-but-cmake-is-using-older-version-how-do">cmake</a>时指定路径:</p></li>
+</ul>
+<pre><code class="hljs">    $ cmake -DPYTHON_LIBRARY=`python-config --prefix`/lib/libpython2.7.dylib -DPYTHON_INCLUDE_DIR=`python-config --prefix`/include/python2.7/ ..
+</code></pre>
+<p>如果从二进制包中安装PySINGA,例如debian或wheel,那么你需要改变python解释器的路径,例如,重新设置$PATH,并把Python的正确路径放在前面的位置。</p>

+<p>要构建GPU版的SINGA,计算机必须装备有Nvida GPU,而且需要安装CUDA driver(&gt;=384.81)、CUDA toolkit(&gt;=9)和cuDNN(&gt;=7)。以下两个Docker镜像提供了构建环境:</p>
+<ol>
+<li>apache/singa:conda-cuda9.0</li>
+<li>apache/singa:conda-cuda10.0</li>
+</ol>
+<p>构建环境准备好后,需要先导出CUDA版本,然后运行conda命令构建SINGA:</p>

+<p>若要上传到anaconda云端供他人下载安装,需要在 anaconda 上注册一个账号,才能<a href="https://docs.anaconda.com/anaconda-cloud/user-guide/getting-started/">上传包</a>:</p>
+<pre><code class="hljs css language-shell">conda install anaconda-client

+anaconda upload -l main &lt;path to the package file&gt;
+</code></pre>
+<p>将包上传到云端后,您可以在<a href="https://anaconda.org/">Anaconda Cloud</a>上看到,也可以通过以下命令查看:</p>
+<pre><code class="hljs css language-shell">conda search -c &lt;anaconda username&gt; singa
+</code></pre>
+<p>每个特定的SINGA软件包都由版本和构建字符串来标识。要安装一个特定的SINGA包,需要提供所有信息,例如:</p>
+<pre><code class="hljs css language-shell">conda install -c &lt;anaconda username&gt; -c conda-forge singa=2.1.0.dev=cpu_py36
+</code></pre>
+<p>为了使安装命令简单化,您可以创建以下附加包,这些包依赖于最新的CPU和GPU SINGA包:</p>
+<pre><code class="hljs css language-console"><span class="hljs-meta">#</span><span class="bash"> <span class="hljs-keyword">for</span> singa-cpu</span>

+<p>因此,当您运行:</p>
+<pre><code class="hljs css language-shell">conda install -c &lt;anaconda username&gt; -c conda-forge singa-xpu
+</code></pre>
+<p>时(<code>xpu</code>表示'cpu' or 'gpu'), 相应的真正的SINGA包将作为依赖库被安装。</p>

+</code></pre>
+<p>CMake选项的详细内容在本页最后一节解释,上面最后一条命令是安装Python包。你也可以运行<code>pip install -e .</code>,它可以创建符号链接,而不是将 Python 文件复制到 site-package 文件夹中。</p>
+<p>如果SINGA在ENABLE_TEST=ON的情况下编译,您可以通过以下方式运行单元测试:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> ./bin/test_singa</span>
+</code></pre>

+<p>SINGA使用opencl-headers和viennacl(版本1.7.1及以上)来支持OpenCL,它们可以通过如下方式安装:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">#</span><span class="bash"> On Ubuntu 16.04</span>
+<span class="hljs-meta">$</span><span class="bash"> sudo apt-get install opencl-headers, libviennacl-dev</span>

+<span class="hljs-meta">$</span><span class="bash"> sudo yum install opencl-headers, viennacl</span>
+</code></pre>
+<p>此外,你需要在你想运行OpenCL的平台安装OpenCL Installable Client Driver(ICD)。</p>
+<ul>
+<li>对于AMD和Nvidia的GPU,驱动包也应该安装与之匹配的OpenCL ICD。</li>
+<li>对于Intel的CPU和/或GPU,请从<a href="https://software.intel.com/en-us/articles/opencl-drivers">Intel官方网站</a>上获取驱动程序。请注意,该网站上提供的驱动程序只支持最新的CPU和Iris GPU。</li>
+<li>对于旧的Intel CPU,你可以使用beignet-opencl-icd包。</li>
+</ul>
+<p>请注意,目前不建议在CPU上运行OpenCL,因为运行速度会很慢。内存传输是以整数秒为单位的(直观来说,CPU上是1000毫秒,而GPU上是1毫秒)。</p>
+<p>更多关于建立OpenCL工作环境的信息可以在<a href="https://wiki.tiker.net/OpenCLHowTo">这里</a>找到。</p>
+<p>如果ViennaCL的软件包版本不是至少1.7.1,则需要从源码构建它:</p>
+<p>从<a href="https://github.com/viennacl/viennacl-dev">这个git repo</a>clone版本库,切换(checkout)到release-1.7.1分支,然后构建它,并把项目路径添加到PATH,再把构建的库文件添加到LD_LIBRARY_PATH。</p>

+<ul>
+<li><p>Q: 'import singa'阶段报错</p>
+<p>A: 请检查<code>python -c &quot;from singa import _singa_wrap</code>中的详细错误。有时是由依赖库引起的,比如protobuf有多个版本,cudnn缺失,numpy版本不匹配等问题。下面展示了不同情况下的解决方案</p>
+<ol>
+<li><p>检查cudnn和cuda。如果cudnn缺失或与wheel包的版本不一致,你可以下载正确的cudnn版本到~/local/cudnn/,然后:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> <span class="hljs-built_in">echo</span> <span class="hljs-string">"export LD_LIBRARY_PATH=/home/&lt;yourname&gt;/local/cudnn/lib64:<span class="hljs-variable">$LD_LIBRARY_PATH</span>"</span> &gt;&gt; ~/.bashrc</span>
+</code></pre></li>
+<li><p>如果是protobuf的问题。你可以将protobuf (3.6.1)从源码安装到本地文件夹,比如 ~/local/,解压tar文件,然后:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> ./configure --prefix=/home/&lt;yourname&gt;<span class="hljs-built_in">local</span></span>
+<span class="hljs-meta">$</span><span class="bash"> make &amp;&amp; make install</span>
+<span class="hljs-meta">$</span><span class="bash"> <span class="hljs-built_in">echo</span> <span class="hljs-string">"export LD_LIBRARY_PATH=/home/&lt;yourname&gt;/local/lib:<span class="hljs-variable">$LD_LIBRARY_PATH</span>"</span> &gt;&gt; ~/.bashrc</span>
+<span class="hljs-meta">$</span><span class="bash"> <span class="hljs-built_in">source</span> ~/.bashrc</span>
+</code></pre></li>
+<li><p>如果找不到包括python在内的其他类库,则使用<code>pip</code>或<code>conda</code>创建虚拟环境.</p></li>
+<li><p>如果不是上述原因造成的,请到<code>_singa_wrap.so</code>文件夹中查看:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> python</span>
+<span class="hljs-meta">&gt;</span><span class="bash">&gt; import importlib</span>
+<span class="hljs-meta">&gt;</span><span class="bash">&gt; importlib.import_module(<span class="hljs-string">'_singa_wrap'</span>)</span>
+</code></pre>
+<p>来检查错误信息。例如,如果是numpy的版本不匹配,错误信息会是:</p>
+<pre><code class="hljs css language-shell">RuntimeError: module compiled against API version 0xb but this version of numpy is 0xa
+</code></pre>
+<p>那么你就需要更新numpy到更高版本。</p></li>
+</ol></li>
+</ul>
+<ul>
+<li><p>Q: 运行<code>cmake ...</code>时出错,找不到依赖库。</p>
+<p>A: 如果你还没有安装这些依赖库,请先安装它们。如果你在系统文件夹之外的文件夹中安装了库,例如/usr/local,那您需要手动导出以下变量:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> <span class="hljs-built_in">export</span> CMAKE_INCLUDE_PATH=&lt;path to your header file folder&gt;</span>

+</code></pre></li>
+</ul>
+<ul>
+<li><p>Q: 来自<code>make</code>的错误,例如linking阶段的错误.</p>
+<p>A: 如果您的库文件在系统默认路径以外的其他文件夹中,则需要手动导出以下变量。</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> <span class="hljs-built_in">export</span> LIBRARY_PATH=&lt;path to your lib file folder&gt;</span>
+<span class="hljs-meta">$</span><span class="bash"> <span class="hljs-built_in">export</span> LD_LIBRARY_PATH=&lt;path to your lib file folder&gt;</span>
+</code></pre></li>
+</ul>
+<ul>
+<li><p>Q: 来自头文件的错误,例如'cblas.h文件不存在'</p>
+<p>A: 您需要手动将cblas.h的文件夹包含在CPLUS_INCLUDE_PATH中,例如:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> <span class="hljs-built_in">export</span> CPLUS_INCLUDE_PATH=/opt/OpenBLAS/include:<span class="hljs-variable">$CPLUS_INCLUDE_PATH</span></span>
+</code></pre></li>
+<li><p>Q: 在编译SINGA时,我收到错误信息<code>SSE2 instruction set not enabled</code></p>
+<p>A:您可以尝试如下指令:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> make CFLAGS=<span class="hljs-string">'-msse2'</span> CXXFLAGS=<span class="hljs-string">'-msse2'</span></span>
+</code></pre></li>
+<li><p>Q:当试图导入.py文件时,从google.protobuf.internal收到<code>ImportError: cannot import name enum_type_wrapper</code>。</p>
+<p>A: 您需要安装protobuf的Python绑定包,它可以通过如下方式安装:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> sudo apt-get install protobuf</span>
+</code></pre>
+<p>或从源文件编译:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> <span class="hljs-built_in">cd</span> /PROTOBUF/SOURCE/FOLDER</span>
+<span class="hljs-meta">$</span><span class="bash"> <span class="hljs-built_in">cd</span> python</span>
+<span class="hljs-meta">$</span><span class="bash"> python setup.py build</span>
+<span class="hljs-meta">$</span><span class="bash"> python setup.py install</span>
+</code></pre></li>
+<li><p>Q: 当我从源码构建OpenBLAS时,被告知需要一个Fortran编译器。</p>
+<p>A: 您可以通过如下方式编译OpenBLAS:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> make ONLY_CBLAS=1</span>
+</code></pre>
+<p>或者通过如下方式安装:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> sudo apt-get install libopenblas-dev</span>
+</code></pre></li>
+<li><p>Q: 当我构建协议缓冲区时,它报告说在<code>/usr/lib64/libstdc++.so.6</code>中没有找到<code>GLIBC++_3.4.20</code>?</p>
+<p>A: 这意味着链接器找到了libstdc++.so.6,但该库属于旧的GCC(用于编译和链接程序的GCC)版本。此程序依赖于新的libstdc++中定义的代码,而该代码属于较新版本的GCC,所以必须告诉链接器如何找到较新的libstdc++共享库。最简单的解决方法是找到正确的libstdc++,并将其导出到LD_LIBRARY_PATH。例如,如果下面命令的输出中列出了GLIBC++_3.4.20:</p>
+<pre><code class="hljs">  $ strings /usr/local/lib64/libstdc++.so.6|grep GLIBC++
+</code></pre>
+<p>那么接下来需要设置环境变量为:</p>
+<pre><code class="hljs">  $ export LD_LIBRARY_PATH=/usr/local/lib64:$LD_LIBRARY_PATH
+</code></pre></li>
+<li><p>Q: 当构建glog时,报告说 &quot;src/logging_unittest.cc:83:20: error: 'gflags' is not a namespace-name&quot;。</p>
+<p>A: 可能是由于安装的gflags用了不同的命名空间,比如 &quot;google&quot;,所以glog找不到'gflags'的命名空间。实际上建立glog并不需要gflags,所以你可以修改configure.ac文件来忽略gflags。</p>
+<pre><code class="hljs">  1. cd to glog src directory
+  2. change line 125 of configure.ac  to &quot;AC_CHECK_LIB(gflags, main, ac_cv_have_libgflags=0, ac_cv_have_libgflags=0)&quot;
+  3. autoreconf
+</code></pre>
+<p>执行上述命令后,就可以重新构建glog了。</p></li>
+<li><p>Q: 在使用虚拟环境时,每次运行pip install,都会重新安装numpy。但是,当运行<code>import numpy</code>时,numpy并没有被调用。</p>
+<p>A: 可能是由于<code>PYTHONPATH</code>造成的,在使用虚拟环境时,应将<code>PYTHONPATH</code>设置为空,以避免与虚拟环境本身的路径冲突。</p></li>
+<li><p>Q: 当从源代码编译PySINGA时,由于缺少&lt;numpy/objectarray.h&gt;,出现的编译错误。</p>
+<p>A: 请安装numpy并导出numpy头文件的路径为</p>
+<pre><code class="hljs">  $ export CPLUS_INCLUDE_PATH=`python -c &quot;import numpy; print numpy.get_include()&quot;`:$CPLUS_INCLUDE_PATH
+</code></pre></li>
+<li><p>Q: 当我在Mac OS X中运行SINGA时,报错 &quot;Fatal Python error:
+PyThreadState_Get: no current thread Abort trap: 6&quot;</p>
+<p>A: 这个错误通常发生在系统上有多个版本的Python,并且是通过pip安装的SINGA (通过conda安装时不会出现这个问题),例如,操作系统自带的版本和Homebrew安装的版本。PySINGA所链接的Python必须与Python解释器(interpreter)相同。 您可以通过 <code>which python</code> 检查您的解释器路径并通过<code>otool -L &lt;path to _singa_wrap.so&gt;</code>检查PySINGA链接的Python路径。要解决这个问题,请用正确的 Python 版本编译 SINGA。需要注意的是,如果您从源码编译 PySINGA,您需要在调用<a href="http://stackoverflow.com/questions/15291500/i-have-2-versions-of-python-installed-but-cmake-is-using-older-version-how-do">cmake</a>时指定路径:</p></li>
+</ul>
+<pre><code class="hljs">    $ cmake -DPYTHON_LIBRARY=`python-config --prefix`/lib/libpython2.7.dylib -DPYTHON_INCLUDE_DIR=`python-config --prefix`/include/python2.7/ ..
+</code></pre>
+<p>如果从二进制包中安装PySINGA,例如debian或wheel,那么你需要改变python解释器的路径,例如,重新设置$PATH,并把Python的正确路径放在前面的位置。</p>

+<p>SINGA代码库在<a href="http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml">CPP</a>和<a href="http://google.github.io/styleguide/pyguide.html">Python</a>代码中都遵循Google风格。</p>
+<p>强制执行Google编码风格的一个简单方法是使用Visual Studio Code编辑器中的linting和格式化工具:</p>
+<ul>
+<li><a href="https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools">C/C++扩展</a></li>
+<li><a href="https://marketplace.visualstudio.com/items?itemName=ms-python.python">Python扩展</a></li>

+<li><a href="https://marketplace.visualstudio.com/items?itemName=xaver.clang-format">Clang-Format</a></li>
+</ul>
+<p>安装扩展后,编辑<code>settings.json</code>文件:</p>
+<pre><code class="hljs css language-json">{
+  <span class="hljs-attr">"[cpp]"</span>: {
+    <span class="hljs-attr">"editor.defaultFormatter"</span>: <span class="hljs-string">"xaver.clang-format"</span>

+<p>最理想的情况是所有贡献者都使用相同版本的代码格式化工具(clang-format 9.0.0和yapf 0.29.0),这样在不同PR中的代码格式化就会完全相同,从而摆脱github pull request冲突。</p>
+<p>首先,安装LLVM 9.0,它提供了clang-format 9.0.0版本,LLVM的下载页面如下:</p>
+<ul>
+<li><p><a href="http://releases.llvm.org/download.html#9.0.0">LLVM</a></p>
+<ul>
+<li><p>Ubuntu系统:</p>
+<pre><code class="hljs css language-sh">sudo apt-get install clang-format-9
+</code></pre></li>
+<li><p>Windows系统,下载预编译包并安装。</p></li>
+</ul></li>
+</ul>
+<p>然后,安装cpplint, pylint和yapf</p>
+<ul>
+<li><p>Ubuntu或OSX:</p>
+<pre><code class="hljs"><span class="hljs-meta">$</span><span class="bash"> sudo pip install cpplint</span>
+<span class="hljs-meta">$</span><span class="bash"> <span class="hljs-built_in">which</span> cpplint</span>

+<span class="hljs-meta">$</span><span class="bash"> pip install pylint</span>
+</code></pre></li>
+<li><p>Windows: 安装Anaconda进行包管理</p>
+<pre><code class="hljs">$ pip <span class="hljs-keyword">install</span> cpplint

+<ul>
+<li>配置后,在编辑源代码文件时,linting会自动启用。错误和警告会在Visual Studio Code <code>PROBLEMS</code>面板中列出。</li>

+<p>推荐使用Visual Studio Code作为编辑器。可以安装Python、C/C++、代码拼写检查器、autoDocstring、vim、远程开发等扩展。这些扩展的参考配置(即<code>settings.json</code>)可以在<a href="https://gist.github.com/nudles/3d23cfb6ffb30ca7636c45fe60278c55">这里</a>查看。</p>
+<p>如果更新CPP代码,需要从<a href="/docs/3.3.0_Chinese/build">源文件</a>重新编译SINGA。建议使用<code>*-devel Docker</code>镜像中的原生构建工具或使用<code>conda build</code>。</p>
+<p>如果要只更新Python代码,您可以安装一次SINGA,然后复制更新后的Python文件来替换Python安装文件夹中的文件。</p>

+<p>强制执行Google编码风格的一个简单方法是使用Visual Studio Code编辑器中的linting和格式化工具:</p>
+<ul>
+<li><a href="https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools">C/C++扩展</a></li>

+<li><a href="https://marketplace.visualstudio.com/items?itemName=xaver.clang-format">Clang-Format</a></li>
+</ul>
+<p>安装扩展后,编辑<code>settings.json</code>文件:</p>
+<pre><code class="hljs css language-json">{
+  <span class="hljs-attr">"[cpp]"</span>: {
+    <span class="hljs-attr">"editor.defaultFormatter"</span>: <span class="hljs-string">"xaver.clang-format"</span>

+<p>最理想的情况是所有贡献者都使用相同版本的代码格式化工具(clang-format 9.0.0和yapf 0.29.0),这样在不同PR中的代码格式化就会完全相同,从而摆脱github pull request冲突。</p>
+<p>首先,安装LLVM 9.0,它提供了clang-format 9.0.0版本,LLVM的下载页面如下:</p>
+<ul>
+<li><p><a href="http://releases.llvm.org/download.html#9.0.0">LLVM</a></p>
+<ul>
+<li><p>Ubuntu系统:</p>
+<pre><code class="hljs css language-sh">sudo apt-get install clang-format-9
+</code></pre></li>
+<li><p>Windows系统,下载预编译包并安装。</p></li>
+</ul></li>
+</ul>
+<p>然后,安装cpplint, pylint和yapf</p>
+<ul>
+<li><p>Ubuntu或OSX:</p>
+<pre><code class="hljs"><span class="hljs-meta">$</span><span class="bash"> sudo pip install cpplint</span>
+<span class="hljs-meta">$</span><span class="bash"> <span class="hljs-built_in">which</span> cpplint</span>

+<span class="hljs-meta">$</span><span class="bash"> pip install pylint</span>
+</code></pre></li>
+<li><p>Windows: 安装Anaconda进行包管理</p>
+<pre><code class="hljs">$ pip <span class="hljs-keyword">install</span> cpplint

+<ul>
+<li>配置后,在编辑源代码文件时,linting会自动启用。错误和警告会在Visual Studio Code <code>PROBLEMS</code>面板中列出。</li>

+<p>推荐使用Visual Studio Code作为编辑器。可以安装Python、C/C++、代码拼写检查器、autoDocstring、vim、远程开发等扩展。这些扩展的参考配置(即<code>settings.json</code>)可以在<a href="https://gist.github.com/nudles/3d23cfb6ffb30ca7636c45fe60278c55">这里</a>查看。</p>
+<p>如果更新CPP代码,需要从<a href="/docs/3.3.0_Chinese/build">源文件</a>重新编译SINGA。建议使用<code>*-devel Docker</code>镜像中的原生构建工具或使用<code>conda build</code>。</p>
+<p>如果要只更新Python代码,您可以安装一次SINGA,然后复制更新后的Python文件来替换Python安装文件夹中的文件。</p>

 <p>然后,python接口提供了一个<a href="https://github.com/apache/singa/blob/master/python/singa/opt.py">DistOpt</a>类来封装一个<a href="https://github.com/apache/singa/blob/master/python/singa/opt.py">optimizer</a>对象,以执行基于MPI或Multiprocess的分布式训练。在初始化过程中,它创建了一个NCCL communicator对象(来自于上面小节提到的C接口),然后,<code>DistOpt</code>中的每一次all-reduce操作都会用到这个communicator对象。</p>
 <p>在MPI或Multiprocess中,每个进程都有一个独立的rank,它给出了各个进程使用的GPU的信息。训练数据是被拆分的,因此每个进程可以根据一部分训练数据来评估子梯度。一旦每个进程的子梯度被计算出来,就可以将所有进程计算出的子梯度做all-reduce,得到总体随机梯度。</p>

 <p>然后,python接口提供了一个<a href="https://github.com/apache/singa/blob/master/python/singa/opt.py">DistOpt</a>类来封装一个<a href="https://github.com/apache/singa/blob/master/python/singa/opt.py">optimizer</a>对象,以执行基于MPI或Multiprocess的分布式训练。在初始化过程中,它创建了一个NCCL communicator对象(来自于上面小节提到的C接口),然后,<code>DistOpt</code>中的每一次all-reduce操作都会用到这个communicator对象。</p>
 <p>在MPI或Multiprocess中,每个进程都有一个独立的rank,它给出了各个进程使用的GPU的信息。训练数据是被拆分的,因此每个进程可以根据一部分训练数据来评估子梯度。一旦每个进程的子梯度被计算出来,就可以将所有进程计算出的子梯度做all-reduce,得到总体随机梯度。</p>

+<li><p>将<a href="https://github.com/apache/singa">SINGA Github repository</a> fork到你自己的Github账户。</p></li>
+<li><p>从你自己的git仓库中clone <strong>repo</strong> (short for repository):</p>
+<pre><code class="hljs css language-shell">git clone https://github.com/&lt;Github account&gt;/singa.git
+git remote add upstream https://github.com/apache/singa.git
+</code></pre></li>
+<li><p>创建一个新的分支(例如 <code>feature-foo</code> 或 <code>fixbug-foo</code>),在这个分支上工作并提交你的代码:</p>
+<pre><code class="hljs css language-shell">git checkout dev
+git checkout -b feature-foo
+<span class="hljs-meta">#</span><span class="bash"> write your code</span>
+git add &lt;created/updated files&gt;
+git commit
+</code></pre>
+<p>commit信息应包括:</p>
+<ul>
+<li>一个概括性的标题。</li>
+<li>详细的描述。如果提交是为了修复bug,描述中最好包括问题的简短复现;如果是新功能,可以描述新功能的动机/目的。</li>
+</ul>
+<p>如果您的分支有很多小的commit,您需要通过:</p>
+<pre><code class="hljs css language-shell">git rebase -i &lt;commit id&gt;
+</code></pre>
+<p>你可以<a href="https://help.github.com/en/articles/about-git-rebase">压制和重写</a>提交的内容。</p></li>
+<li><p>当你在写代码的时候,SINGA的<code>dev</code>分支可能已经被别人更新了;在这种情况下,你需要拉取最新的<code>dev</code>分支:</p>
+<pre><code class="hljs css language-shell">git checkout dev
+git pull upstream dev:dev
+</code></pre></li>
+<li><p>将<code>feature-foo</code> <a href="https://git-scm.com/book/en/v2/Git-Branching-Rebasing">rebase</a>到<code>dev</code>分支上,并将提交的内容推送到自己的Github账户(你刚刚创建的新分支),rebase操作是为了清理提交历史。提交当前工作后,应执行以下 git 指令:</p>
+<pre><code class="hljs css language-shell">git checkout feature-foo
+git rebase dev
+git push origin feature-foo:feature-foo
+</code></pre>
+<p>Rebase命令的<a href="https://git-scm.com/book/en/v2/Git-Branching-Rebasing">操作步骤</a>如下: &quot;这个操作的工作原理是进入到两个分支(你所在的分支和你要rebase的分支)的共同来源 -&gt; 获取你所在分支的每次commit所引入的差异 -&gt; 将这些差异保存到临时文件中 -&gt; 将当前分支重置为与你要rebase的分支相同的commit -&gt; 最后依次修改每个差异。&quot;</p>
+<p>因此,执行后,你还是在特性分支上,但你自己的提交ID/hash被改变了,因为diffs是在rebase时提交的;而且你的分支现在有来自<code>dev</code>分支和你自己分支的最新代码。</p></li>
+<li><p>在 Github 网站上创建一个针对 apache/singa <code>dev</code>分支的pull request(PR)。如果你想通知其他在相同文件上工作过的贡献者,你可以在Github上找到文件,然后点击 &quot;Blame&quot;,就可以看到最后修改代码的人的逐行注释。然后,你可以在PR描述中加上@username,就可以立即ping到他们。请说明该贡献是你的原创作品,并且你在项目的开源许可下将该作品授权给项目。你的新分支的进一步提交(例如,bug修复)将由Github自动添加到这个pull request中。</p></li>
+<li><p>接下来等待committer审核PR。在这段时间里,SINGA的<code>dev</code>可能已经被其他人更新了,这时你需要<a href="https://docs.fast.ai/dev/git.html#how-to-keep-your-feature-branch-up-to-date">合并</a>最新的<code>dev</code>来解决冲突。有些人将PR重新<a href="https://github.com/edx/edx-platform/wiki/How-to-Rebase-a-Pull-Request">rebase到最新的dev</a>上,而不是合并。但是,如果其他开发者获取这个PR来添加新的功能,然后再发送PR,那么rebase操作会在未来的PR中引入<strong>重复的提交</strong>(不同的哈希)。关于何时避免使用rebase的细节,请参见<a href="https://www.atlassian.com/git/tutorials/merging-vs-rebasing">The Golden Rule  [...]

+<p>Committer可以将PR合并到上游 repo 的 dev 分支。在合并每一个PR之前,提交者应该做到:</p>
+<ul>
+<li>检查commit信息(内容和格式)</li>
+<li>检查对现有代码的修改,API的变化应该被记录下来</li>
+<li>检查Travis测试结果,检查代码/文档格式和单元测试。</li>
+</ul>
+<p>合并PR的方式有两种:</p>
+<ul>
+<li><p>在Github上,按照<a href="https://gitbox.apache.org/setup/">说明</a>将你的Apache账户与Github账户链接,之后你就可以直接在GitHub上合并PR了。</p></li>
+<li><p>通过命令行合并pull request到<a href="https://github.com/apache/singa/pull/xxx">https://github.com/apache/singa/pull/xxx</a>,应执行以下指令:</p>
+<pre><code class="hljs css language-shell">git clone https://github.com/apache/singa.git
+git remote add asf https://gitbox.apache.org/repos/asf/singa.git
+git fetch origin pull/xxx/head:prxxx

+<p>commit信息应包括:</p>
+<ul>
+<li>一个概括性的标题。</li>
+<li>详细的描述。如果提交是为了修复bug,描述中最好包括问题的简短复现;如果是新功能,可以描述新功能的动机/目的。</li>
+</ul>
+<p>如果您的分支有很多小的commit,您需要通过:</p>
+<pre><code class="hljs css language-shell">git rebase -i &lt;commit id&gt;
+</code></pre>
+<p>你可以<a href="https://help.github.com/en/articles/about-git-rebase">压制和重写</a>提交的内容。</p></li>
+<li><p>当你在写代码的时候,SINGA的<code>dev</code>分支可能已经被别人更新了;在这种情况下,你需要拉取最新的<code>dev</code>分支:</p>
+<pre><code class="hljs css language-shell">git checkout dev
+git pull upstream dev:dev
+</code></pre></li>
+<li><p>将<code>feature-foo</code> <a href="https://git-scm.com/book/en/v2/Git-Branching-Rebasing">rebase</a>到<code>dev</code>分支上,并将提交的内容推送到自己的Github账户(你刚刚创建的新分支),rebase操作是为了清理提交历史。提交当前工作后,应执行以下 git 指令:</p>
+<pre><code class="hljs css language-shell">git checkout feature-foo
+git rebase dev
+git push origin feature-foo:feature-foo
+</code></pre>
+<p>Rebase命令的<a href="https://git-scm.com/book/en/v2/Git-Branching-Rebasing">操作步骤</a>如下: &quot;这个操作的工作原理是进入到两个分支(你所在的分支和你要rebase的分支)的共同来源 -&gt; 获取你所在分支的每次commit所引入的差异 -&gt; 将这些差异保存到临时文件中 -&gt; 将当前分支重置为与你要rebase的分支相同的commit -&gt; 最后依次修改每个差异。&quot;</p>
+<p>因此,执行后,你还是在特性分支上,但你自己的提交ID/hash被改变了,因为diffs是在rebase时提交的;而且你的分支现在有来自<code>dev</code>分支和你自己分支的最新代码。</p></li>
+<li><p>在 Github 网站上创建一个针对 apache/singa <code>dev</code>分支的pull request(PR)。如果你想通知其他在相同文件上工作过的贡献者,你可以在Github上找到文件,然后点击 &quot;Blame&quot;,就可以看到最后修改代码的人的逐行注释。然后,你可以在PR描述中加上@username,就可以立即ping到他们。请说明该贡献是你的原创作品,并且你在项目的开源许可下将该作品授权给项目。你的新分支的进一步提交(例如,bug修复)将由Github自动添加到这个pull request中。</p></li>
+<li><p>接下来等待committer审核PR。在这段时间里,SINGA的<code>dev</code>可能已经被其他人更新了,这时你需要<a href="https://docs.fast.ai/dev/git.html#how-to-keep-your-feature-branch-up-to-date">合并</a>最新的<code>dev</code>来解决冲突。有些人将PR重新<a href="https://github.com/edx/edx-platform/wiki/How-to-Rebase-a-Pull-Request">rebase到最新的dev</a>上,而不是合并。但是,如果其他开发者获取这个PR来添加新的功能,然后再发送PR,那么rebase操作会在未来的PR中引入<strong>重复的提交</strong>(不同的哈希)。关于何时避免使用rebase的细节,请参见<a href="https://www.atlassian.com/git/tutorials/merging-vs-rebasing">The Golden Rule  [...]

 <p>神经网络中的前向和反向传播可以用一组操作来表示,比如卷积和池化。每个操作都需要一些输入的<a href="./tensor">tensors</a>,并应用一个<a href="./autograd">operator</a>来生成输出的张量。通过将每个运算符表示为一个节点,将每个张量表示为一条边,所有的运算就形成了一个计算图。有了计算图,可以通过调度运算的执行和内存的智能分配/释放来进行速度和内存优化。在SINGA中,用户只需要使用<a href="https://github.com/apache/singa/blob/master/python/singa/model.py">Model</a> API定义神经网络模型,计算图则会在C++后台自动构建和优化。</p>
 <p>这样,一方面,用户使用<a href="./graph">Model</a> API按照PyTorch那样的命令式编程风格实现网络。而与PyTorch在每次迭代中重新创建操作不同的是,SINGA在第一次迭代后就会缓冲操作,隐式地创建计算图(当该功能被启用时)。因此,另一方面,SINGA的计算图与使用声明式编程的库(如TensorFlow)创建的计算图类似,因而它可以享受在图上进行的优化。</p>

 <p>神经网络中的前向和反向传播可以用一组操作来表示,比如卷积和池化。每个操作都需要一些输入的<a href="./tensor">tensors</a>,并应用一个<a href="./autograd">operator</a>来生成输出的张量。通过将每个运算符表示为一个节点,将每个张量表示为一条边,所有的运算就形成了一个计算图。有了计算图,可以通过调度运算的执行和内存的智能分配/释放来进行速度和内存优化。在SINGA中,用户只需要使用<a href="https://github.com/apache/singa/blob/master/python/singa/model.py">Model</a> API定义神经网络模型,计算图则会在C++后台自动构建和优化。</p>
 <p>这样,一方面,用户使用<a href="./graph">Model</a> API按照PyTorch那样的命令式编程风格实现网络。而与PyTorch在每次迭代中重新创建操作不同的是,SINGA在第一次迭代后就会缓冲操作,隐式地创建计算图(当该功能被启用时)。因此,另一方面,SINGA的计算图与使用声明式编程的库(如TensorFlow)创建的计算图类似,因而它可以享受在图上进行的优化。</p>

+<p>推荐使用<a href="https://conda.io/miniconda.html">Miniconda3</a>来配合SINGA使用,安装miniconda后,执行以下命令之一安装SINGA。</p>
+<ol>
+<li>只使用CPU
+<a href="https://colab.research.google.com/drive/17RA056Brwk0vBQTFaZ-l9EbqwADO0NA9?usp=sharing"><img src="https://colab.research.google.com/assets/colab-badge.svg" alt="Open In Colab"></a></li>
+</ol>
+<pre><code class="hljs css language-bash">pip install singa -f http://singa.apache.org/docs/next/wheel-cpu.html --trusted-host singa.apache.org
+</code></pre>
+<p>您可以通过<code>singa==&lt;version&gt;</code>安装特定版本的SINGA,其中<code>&lt;version&gt;</code>字段应被替换,例如<code>3.3.0</code>。可用的SINGA版本在链接中列出。</p>
+<p>要安装最新的开发版本,请将链接替换为
+<a href="http://singa.apache.org/docs/next/wheel-cpu-dev.html">http://singa.apache.org/docs/next/wheel-cpu-dev.html</a></p>
+<ol start="2">
+<li>使用CUDA和cuDNN的GPU
+<a href="https://colab.research.google.com/drive/1W30IPCqj5fG8ADAQsFqclaCLyIclVcJL?usp=sharing"><img src="https://colab.research.google.com/assets/colab-badge.svg" alt="Open In Colab"></a></li>
+</ol>
+<pre><code class="hljs css language-bash">pip install singa -f http://singa.apache.org/docs/next/wheel-gpu.html --trusted-host singa.apache.org
+</code></pre>
+<p>您也可以配置SINGA版本和CUDA版本,比如<code>singa==3.3.0+cuda10.2</code>,SINGA版本和CUDA版本的可用组合在链接中列出。</p>
+<p>要安装最新的开发版本,请将链接替换为
+<a href="http://singa.apache.org/docs/next/wheel-gpu-dev.html">http://singa.apache.org/docs/next/wheel-gpu-dev.html</a></p>
+<p>注意:你本地Python环境的Python版本将被用来寻找相应的wheel包。例如,如果你本地的Python是3.6,那么就会通过pip选择在Python 3.6上编译的wheel包并安装。事实上,wheel文件的名称包括SINGA版本、CUDA版本和Python版本。因此,<code>pip</code>知道要下载和安装哪个wheel文件。</p>
+<p>参考setup.py文件顶部的注释,了解如何构建wheel包。</p>
+<p>如果运行以下命令没有报错:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> python -c <span class="hljs-string">"from singa import tensor"</span></span>
+</code></pre>
+<p>那么SINGA就安装成功了。</p>

+<li><p>Q: <code>from singa import tensor</code>错误</p>
+<p>A: 执行下面的命令,检查详细的错误:</p>
+<pre><code class="hljs css language-shell">python -c  "from singa import _singa_wrap"
+<span class="hljs-meta">#</span><span class="bash"> go to the folder of _singa_wrap.so</span>

+</code></pre>
+<p><code>_singa_wrap.so</code> 的文件夹是 <code>~/miniconda3/lib/python3.7/site-packages/singa</code>。通常情况下,这个错误是由于依赖的库不匹配或缺失造成的,例如 cuDNN 或 protobuf。解决方法是创建一个新的虚拟环境,并在该环境中安装SINGA,例如:</p></li>

+<ul>
+<li><p>Q: 使用虚拟环境时,每次安装SINGA时,都会重新安装numpy。但是,当我运行<code>import numpy</code>时,numpy没有被使用。</p>
+<p>A:
+这可能是由<code>PYTHONPATH</code>环境变量引起的,在使用虚拟环境时,应将其设置为空,以避免与虚拟环境的路径冲突。</p></li>
+<li><p>Q: 当我在Mac OS X中运行SINGA时,得到如下错误 &quot;Fatal Python error:
+PyThreadState_Get: no current thread Abort trap: 6&quot;</p>
+<p>A: 这个错误通常发生在系统中有多个 Python 版本的时候,例如,操作系统自带的版本和 Homebrew 安装的版本。SINGA链接的Python必须与Python解释器相同。您可以通过<code>which python</code>来检查解释器python版本并通过<code>otool -L &lt;path to _singa_wrap.so&gt;</code> 检查 SINGA 链接的 Python,如果通过conda安装SINGA,这个问题应该可以解决。</p></li>

+<p>推荐使用<a href="https://conda.io/miniconda.html">Miniconda3</a>来配合SINGA使用,安装miniconda后,执行以下命令之一安装SINGA。</p>
+<ol>
+<li>只使用CPU
+<a href="https://colab.research.google.com/drive/17RA056Brwk0vBQTFaZ-l9EbqwADO0NA9?usp=sharing"><img src="https://colab.research.google.com/assets/colab-badge.svg" alt="Open In Colab"></a></li>
+</ol>
+<pre><code class="hljs css language-bash">pip install singa -f http://singa.apache.org/docs/next/wheel-cpu.html --trusted-host singa.apache.org
+</code></pre>
+<p>您可以通过<code>singa==&lt;version&gt;</code>安装特定版本的SINGA,其中<code>&lt;version&gt;</code>字段应被替换,例如<code>3.3.0</code>。可用的SINGA版本在链接中列出。</p>
+<p>要安装最新的开发版本,请将链接替换为
+<a href="http://singa.apache.org/docs/next/wheel-cpu-dev.html">http://singa.apache.org/docs/next/wheel-cpu-dev.html</a></p>
+<ol start="2">
+<li>使用CUDA和cuDNN的GPU
+<a href="https://colab.research.google.com/drive/1W30IPCqj5fG8ADAQsFqclaCLyIclVcJL?usp=sharing"><img src="https://colab.research.google.com/assets/colab-badge.svg" alt="Open In Colab"></a></li>
+</ol>
+<pre><code class="hljs css language-bash">pip install singa -f http://singa.apache.org/docs/next/wheel-gpu.html --trusted-host singa.apache.org
+</code></pre>
+<p>您也可以配置SINGA版本和CUDA版本,比如<code>singa==3.3.0+cuda10.2</code>,SINGA版本和CUDA版本的可用组合在链接中列出。</p>
+<p>要安装最新的开发版本,请将链接替换为
+<a href="http://singa.apache.org/docs/next/wheel-gpu-dev.html">http://singa.apache.org/docs/next/wheel-gpu-dev.html</a></p>
+<p>注意:你本地Python环境的Python版本将被用来寻找相应的wheel包。例如,如果你本地的Python是3.6,那么就会通过pip选择在Python 3.6上编译的wheel包并安装。事实上,wheel文件的名称包括SINGA版本、CUDA版本和Python版本。因此,<code>pip</code>知道要下载和安装哪个wheel文件。</p>
+<p>参考setup.py文件顶部的注释,了解如何构建wheel包。</p>
+<p>如果运行以下命令没有报错:</p>
+<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> python -c <span class="hljs-string">"from singa import tensor"</span></span>
+</code></pre>
+<p>那么SINGA就安装成功了。</p>

+<p>最后,如果我们想做迁移学习,我们可以定义一个名为<strong>Trans</strong>的函数,在onnx模型后追加一些层。为了演示,代码中只在onnx模型后追加了几个线性(全连接)和relu。可以定义一个transfer_learning函数来处理transfer-learning模型的训练过程,而训练的标签和前面一个的一样。</p>
